On ia64 ioremap_nocache fails if attributes don't match. Not other architectures does this, and we plan to get rid of ioremap_nocache. So get rid of the special semantics and define ioremap_nocache in terms of ioremap as no portable driver could rely on the behavior anyway. However x86 implements ioremap_uc in a similar way as the ia64 version of ioremap_nocache, in that it ignores the firmware tables. Switch ia64 to override ioremap_uc instead.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
